HESI A2 Vocabulary 2023 Questions
Question 1 of 5
Select the meaning of the word 'undulate' in the sentence: 'Each shiver made his muscles undulate beneath his skin.'
Correct Answer: A
Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.
Question 2 of 5
Select the meaning of the word 'spurious' in the sentence: 'The researcher's spurious argument confused even the experts.'
Correct Answer: A
Rationale: The correct answer is A: Bogus. 'Spurious' means not genuine or false, which aligns with 'bogus.' The sentence suggests the researcher made a misleading or false argument. Choice B, obscure, means unclear or hard to understand, which doesn't fit the context. Choice C, baffling, means confusing or perplexing, but doesn't capture the deceitful nature of 'spurious.' Choice D, outrageous, means shocking or offensive, which is not the same as being false or deceptive. Therefore, 'bogus' is the best fit for the context of the sentence.
Question 3 of 5
What is the best description for the abbreviation EEG?
Correct Answer: A
Rationale: The correct answer is A: A test of brain activity. EEG stands for Electroencephalogram, which is a test that measures electrical activity in the brain. This test is commonly used to diagnose epilepsy, sleep disorders, and other neurological conditions. Choice B is incorrect as EEG is not a service but a diagnostic test. Choice C is incorrect as EEG does not monitor heartbeats. Choice D is incorrect as EEG has no relation to dentistry. EEG specifically focuses on brain activity, making choice A the most appropriate description.
Question 4 of 5
A remedy may cure certain ailments. Another word for this might be ___________.
Correct Answer: C
Rationale: The correct answer is C: nostrum. A remedy is a substance or treatment that cures ailments. "Nostrum" is a synonym for remedy or cure, making it the most appropriate choice. A: inoculation refers to the process of introducing a vaccine to prevent disease. B: indicator is something that provides information or points out a condition, not necessarily a cure. D: serum is a component of blood and not specifically related to curing ailments. Therefore, C is the correct answer because it directly relates to the concept of a remedy curing ailments.
Question 5 of 5
A vertiginous patient is ___________.
Correct Answer: D
Rationale: The correct answer is D: dizzy. Vertigo is a sensation of spinning or dizziness. Patients experiencing vertigo feel as if they or their surroundings are moving when they are not. Therefore, a vertiginous patient would be dizzy. Choices A, B, and C are incorrect because being on a liquid diet, lying flat, or being burned do not directly relate to vertigo or the symptoms associated with it.
